I cleaned a 100% wool sheep skin rug,The problem my client spilled a class of wine on it and it looked terrible.I sprayed my procyon on it and watched it disappear..The stuff is amazing!! I normally use bio-based products and figure i would give procyon a try and it cleans berber and wool awesome!!! just thought i would share with everyone..Its a pretty safe product but most of my products have to be bio-based..
